ADP 4-0 and ADRP 4-0, Sustainment, supports ADP 3-0 and ADRP 3-0, Unified Land Operations. This principle level doctrine focuses on how the elements of sustainment: logistics, personnel services, and health services support ensure operational success by giving Army forces operational reach, freedom of action, and prolong endurance. It serves as the doctrinal bridge fostering the understanding of the seamless nature and essential linkages of sustainment capabilities from the strategic base to tactical level operations. Figure 1 reflects the doctrine for how sustainment supports a commander's ability to conduct decisive action. ADP 3-0, Unified Land Operations, describes the Army's participation in unified action as part of the joint force. The "Anticipated Operational Environment" describes the challenges the Army may face in ever increasingly complex operational environments. ADP 4-0, Sustainment, in a similar fashion, establishes the basic doctrinal framework for the critical role sustainment plays in the success of operations. The success of the joint sustainment environment occurs through constant and deliberate coordination, collaboration, and synchronization of intergovernmental agencies and joint and Service sustainment capabilities, intrinsically linked across all sustainment elements and across all levels of war. Army sustainment, consisting of its historically provided capabilities of logistics, personnel services and health service support, is enhanced by joint interdependence. Sustainment is also enabled by a strategic base which provides the essential links to strategic and national enablers and serves as the point around which theater sustainment is initiated and maintained. Sustainment capabilities supported by the national strategic base and synchronized with theater operations are essential for operational reach, freedom of action, and prolong endurance.
